Application August as, 1949, Serial miners This invention relates to scrapers having buck etsiin combination therewith and particularly devices-for moving dirt and the like, and in particnlar'atractor propelled carrier having a scrapmg blade in the form of a forward scoopwith a bucket positioned to receivexmaterial from the bladeand with hydrauliomeans for actuating the scraping scoop and bucket to scraping and dumpin'g positions. a

The purpose of this invention isto provide a combination scraper and carrier wherein the parts readily pick up and carry dirt-and the like and in which the partsare readily actuated to dump-the-dirt; I

Various types of dirt pushers and movers have been provided and scrapers in the form of buckets have been used for fills and the like but where scrapin buckets of this type havebeen used they are comparativelysmall and many trips are required -With this thought in mind this invention contemplates a scraper in the form of a scoopwith a receiving bucket having an upwardly extended rear end wherein the two elements coact to provide a relatively large bucket-and in which the two partsare separated for dumping.

"The object of" this invention is, therefore, to provide a combination scraper and carrier in which comparatively large quantities of material are handled and in which the device is readily dumped.

Another object of the invention is to provide a combination scraper and carrier in which coinparatively large-quantities of material are handled with very littlepull-ing power.

A further object of'the invention is to provide a combinationdirt scraper and carrier which is of a simple and economical construction.-

With these and other objects and advantages in view the invention embodies a'ch'assis mountedon wheelswi-th a transversely disposed verticallypositioned apron .at the front, a scraper blade forming the forward end; of a forward scoop pivotally mounted in the chassis and'an upended bucketalso pivotally mounted on the chassis and positioned to coact with the scoop and its scraper bladefor providing a carrier.

Other features and advantagesof the invention will appear from the following description taken in connection with the drawings wherein:

Y y 1 Referring now to. the drawings wherein like reference characters denote corresponding -;parts the combination scraper and carrier of this .invention. includes a. scraper blade H which-With the side walls H. and 12 form ascoop 9,;a; bucket l -3upositionedto receive dirt or other material from the scoop, hydraulic cylinders M and l-5, an apron IE and a chassis 'orframe- H which is mounted onwheels i8 and l9.

The scoop 9 and the bucketifi aremounted on a. U-shapedtubular frame having an upper horizontally disposedbar 22' ,andvertical end bars .23: and 24 and the wheels 1.8V and 19 are iournaled. in hubs 25* and; 26 at the lower ends of the members 23. and 24. The chassis or frame I! includes tubular side members 21 and. 28;. ex-;- tended outwardly-from a. tongue 29- and' the rear ends of the sidemembers 21 and 2alarescjonnected to the lower ends-of the members 23" and.

The side plates l I and I2 of the scoop 9 are pivotally attached. by bolts 29 and.30 to-therear ends. of the side beams 21 -and: 28 and these side plates are provided with. brackets 3-. l5: and:v 32,. the ends; of the: bracket .31 being .con'nectedito; the platev liby bolts, 33 and MJandtheJends of the bracket 32. being connected to thepl'ate' ['2 by bolts35and 36i Thebracketfliirof'the plate H; is pivotally cone nectedbyj a pin .31 to the. end of. a; comie'cting: rod 38; of: the hydraulic cylinder '14,, and the: bracket 32: of the plate 1.2: is pivotally connected. by a. pin tflzto the connecting rodv 453 of the, hydraulio cyl q inder i5, and with the hydraulic cylinders pi-ve otal-ly mounted in the outer ends of arm's-4| and 42 extended from the horizontal bar 22 carried by the upper ends of the members 23 and 24; respectively. The seoopis pivoted through the side walls H and t2 thereof on the pins: 29. and 3!} whereby the hydraulic. cylinders will. swing the scoop upwardly about pins 29 and 30 as thepise tons are drawn into the cylindersu-ntilthe; scoop assumes the position shown in Fig-ure '3. The cylinders- M- and I5 are pivotally mounted through bolts 43- .and 44 to the upper ends of the arms 41 and 42, respectively and the arms-are rein-1 forced bybraces 45 and 46, respectively; 1

The arouatelower section of. the bottom of the bucket I3 is shaped as-illustrated in'Figureyzwith reinforcing bars 4'! on the outer surface and with side plates 48 and 49 extended from the edges corresponding with the sides II and I 2 of the scoop 9. The side plates 48 and 49 are also reinforced by braces 50 and respectively and the braces are attached to the side plates by bolts 52. The bucket is pivotally mounted through the upper ends of the braces on the. vertical side members 23' and 24 of the U-shaped frame by bolts 53 and 54 which are held in ears 55 and 58, respectively that extend from the rear surfaces of the vertical members. The brace 50 on one side of the bucket is connected by alinkil to the bolt 84 of the bracket 3! on the side plate H of the scraper and the opposite end of the link is connected by a'bolt 58 to the brace. The brace 5| is also connected by a link 59 to the side wall l2 of the scraper through the bolt 36, the opposite end of the link 59 being connected to the brace 51 by a bolt 60.

The upper ends of the vertical members 23 and 24 of the U-shaped frame are adjustably connected to the members 21 and 28 of the chassis I? by diagonally disposed braces 6i and 62, the brace Bl being pivotally mounted on a'flange 63 of the member 2'! by a bolt 64 and connected t an ear 65 on the upper end of the member 23 by a clamp 66, and the brace 62 is pivotally connected to a flange 81 on the side beam 28 by a bolt 68 with the upper end connected to the member 24 by a clamp 69 which is connected to an ear [0 by a bolt 1 I. By this means the position of the scraper blade l0 may be elevated or lowered in relation to the chassis IL A reinforcing angle 12 is positioned across the rear end of the bucket as shown in Figures 1 and 2 to provide supporting means for the parts thereof.

The apron l6 which is provided with a flange 13 on the upper edge is mounted on a cross bar 14 and supported by braces '15 and 16, the lower ends of which are connected to extensions '11 and 18 on the beams 21 and 28 by bolts l9 and 80, respectively.

The forward end of the tongue 29 may be provided with a clevis 8! or other means by which the device may be attached to a tractor or the like.

With the parts arranged in this manner the combination scraper and carrier is first drawn over dirt or the like with the parts in the position illustrated in Figures 1 and 2 and as the scoop and bucket are filled with dirt the scoop and bucket are adjusted to a position wherein the scraper blade is free of the ground whereby the material may be carried to substantially any point desired. When itis desired to dump the material pressure is applied to the hydraulic jacks or cylinders which actuatethe scoop andbucket to the positions illustrated in Figure 3. Pressure may then be-"applied to the opposite end of the cylinder which will force the scoop and bucket downwardly so that they are returned to the position illustrated in Figures 1 and 2.

It will be understood that modifications may be made in the design and arrangement f the parts without departing from the spirit of the invention.
